It has been more than two years since Greg Oden last played in the NBA, but he never retired.

And when the former No. 1 pick makes himself available, people stand up and take notice -- scrambled eggs for knees or not.

Especially when that player is Oden, a 7-footer who once dominated the college game in his lone season at Ohio State.

Oden showed some serious flashes in the NBA, too. Portland selected him with the top draft pick in 2007, and in the rare moments of good health, he made an instant impact defensively. Also, in his final game with the Trail Blazers (Dec. 1, 2009), Oden snared 20 rebounds.

But, as you probably know, Oden has undergone three microfracture knee surgeries. He played in just a total of 82 games with Portland -- or the equivalent of one season.

He’s now back at Ohio State, taking classes and vowing to return to the NBA. His agent, Mike Conley Sr., has promised that Oden is now 100 percent. Conley has even predicted Oden will become an All-Star.

That would be quite a comeback, and while some teams may feel differently after having worked out Oden, several are ready to take at least take a flyer on him, as reported by FOX Sports Ohio in early January.

Both Cleveland and Charlotte are said to be prepared to make Oden an offer following the Feb. 21 trading deadline. Boston also remains interested, although it’s believed Celtics president of basketball operations Danny Ainge won’t get into any sort of bidding war.

The Cavaliers, however, are under the cap and can afford to take a low-risk-high-reward chance on a player like Oden. Their proposal reportedly will be for two years (the rest of this season and next), with a team option for a third.
